远程教育教师发展途径的成效分析

随着远程教育的快速发展,教师发展问题已经受到远程教育机构越来越多的重视。如何更好地促进远程教育教师的发展,即教师发展途径的问题,在理论和政策上已有诸多探讨,但这些探讨大多是从应然的角度对远程教育教师和教育机构提出的理想化要求,并没有切身关注教师的实际需求、期望和实效。以这一研究视角为切入点,通过调查某开放大学全体专职教师对教师发展途径实效的看法,结果发现：在我国远程教育系统目前主要存在的8种教师发展途径中,＂学历深造＂的认可度最高,＂自我反思＂是最具弹性和自主化的发展途径,＂同行交流与互助＂比＂专家指导＂具有更大的实效,＂校外培训＂比＂校本培训＂的实效更好,＂教研活动＂的实际帮助程度较低,＂竞赛和公开课＂的实效最低。为了促进远程教育教师持续而系统的发展,远程教育机构应积极探索新的远程教育教师发展系统,既要明确身份和定位,从制度和组织层面进行系统规划,又要为教师发展途径的选择提供弹性和灵活性,更要注重教师发展途径具体的实践性和情境性,以此来重构、重组和优化远程教育教师发展系统的可能空间。     

文化批评视阈下的体裁分析研究图景

伯明翰学派文化批评理论洞察话语实践中权力与意识形态的运作,也体察结构性宰制和主体性协商与逆反之间的张力。从文化批评视角考察体裁分析三大流派:悉尼学派具有语言分析的优势,但需配合文化批评的"理论优势"对生活政治性地介入;专门用途英语学派着重语篇目的、功能的解读,也日益重视引入社会批判的维度;新修辞学派关注业务性语篇的写作,弱化了文化批评的立场。传统语言学强调真理性和规约性的逻辑,文化批评则秉持建构性与主体性的旨向。     

车道被占用对城市道路通行能力影响的分析

针对车道被占用对城市道路通行能力的影响,根据所给条件,运用数据统计、车流波动理论等方法,分别建立了道路实际通行能力模型和速度—密度模型,使用了Excel进行求解、作图,进而给出了不同车道被占用时道路横断面实际通行能力的变化过程和差异,以及给定条件下车辆排队长度与事故横断面道路的实际通行能力、事故持续时间和路段上游车流量之间的关系式。     

欧美同学会成立时间考

欧美同学会是民初由顾维钧、周诒春等欧美归国留学生发起成立的留学生联谊团体,在其存续的百年之间,其会员以知识精英的身份在政治、社会、文化舞台上扮演着重要的角色。但长期以来,对于欧美同学会的成立时间,却有1911年、1912年、1913年、1915年四种不同的说法。通过梳理欧美同学会原始会史档案,细考发起人之回忆和当时新闻界之报道,对该会认同的欧美同学会成立于1913年之说,作了详细的分析和推定。     

我国广电类上市公司绩效评价及对策研究

广电类上市公司是传媒产业发展的中坚力量,广电类上市公司经营绩效的高低反映了传媒企业的整体经营状况。基于2008～2012年期间我国6家广电类上市公司的财务数据,运用数据包络分析法,对其经营绩效进行动态评价。研究结果显示：广电类上市公司整体经营效率较高,但不稳定,各公司经营效率差异明显,反映了资源配置不合理。为提高广电类上市公司经营绩效。上市公司必须改变管理模式,优化资源配置,发展核心优质业务,同时加强上市公司之间的合作。     

我国阅读教学的问题与取向：国际阅读教学观察框架的视野

中小学生阅读成效低下,读写表现不佳,已成为世界性难题.而如何提高阅读教学的有效性,提高中小学生的阅读水平,就成为人们面临的重大挑战.国际阅读协会开发的阅读教学观察框架,对我们理解并建构高效的阅读教学具有重要的参考价值.借助观察框架,主要理出了三个相关领域的知识：学生究竟要学什么、教师究竟要教什么与教师究竟如何评价.借此审视我国阅读教学,需要思考如下关键概念：阅读教学的文化氛围,究竟是研究,还是表现;阅读教学的本质,究竟是内容理解,还是意义建构;阅读教学的追求,究竟是教师责任,还是学生责任.而阅读教学的取向应该是：教学即研究,即意义建构,即学生责任.

Identifying Characteristics of Dissemination Success Using an Expert Panel

Although considerable work has been done to develop new educational innovations, few have found widespread acceptance in the classroom. To improve the likelihood of adoption of educational innovations, researchers need to understand why some innovations are adopted and routinely used, while others are not. An initial aspect of the diffusion of innovations, as defined in the classical sociological literature, involves the communication of ideas and concepts related to innovations between individuals. This article presents an expert panel's answer to the following question: “What are the most important characteristics that relate to the dissemination of educational innovations?” As dissemination is a critical facet of the diffusion of an innovation, 45 researchers who received technology and engineering grants from the National Science Foundation (NSF) participated in a Delphi study designed to address this research question. In three rounds, the experts identified and ranked 11 characteristics of educational innovations, 6 characteristics of students, 13 characteristics of faculty members, and 5 characteristics of administrators that can relate to the successful dissemination of educational innovations. The results of this study led to the formation of a Characteristics of Dissemination Success (CODS) framework. This framework offers useful guidance for educational innovators seeking a better understanding of the influences on the dissemination of educational innovations.     

Suitability of Stem Latex of Jatropha Gossypifolia as a Protein Precipitant for Biochemical Analysis

The extract of Jatropha Gossypifolia stem was obtained by cutting the stem with a sharp knife and the fluid expressed out. The suitability of the stem latex extract as a precipitant for biochemical analysis was determined. The precipitating efficacy of the extract for creatinine and protein estimation was found to be optimum at 1/4 and 1/5 dilutions respectively aqueous solution. Plasma protein was precipitated with stem extract of J. Gossypifolia at the stated dilution. The mean plasma creatinine values obtained from 0.5 % sodium tungstate as a protein precipitant were compared with the values of plasma creatinine obtained when ¼ dilution of stem extract of J. Gossypifolia was used as protein precipitant. Similarly mean cerebrospinal fluid (CSF) and urinary protein values obtained from 3 % Tricholoro-acetic acid as protein precipitant were compared with values obtained from 1/5 dilution of stem extract of J. Gossypifolia as protein precipitant. The values obtained from the stem latex extract at the stated dilutions were comparable with values obtained from the conventional protein precipitants (p < 0.05). The stem latex extract of J. Gossypifolia is suitable as a protein precipitant for creatinine, CSF and urinary protein estimations. However further work need to be done to purify the extract and determine the exact concentration at the stated dilutions as well as the active ingredient in stem latex.
